Field connectivity for responders

Field offices online in days, and secure.

Responders need connectivity the day they arrive: for coordination, registration, payments and safety. A deployable kit of satellite and cellular backhaul, Wi-Fi and mesh, power and security brings a field office or warehouse online within days and keeps it running for as long as the operation lasts.

  1. Humanitarian · Field connectivity for responders

    Connected on day one

    Responders need connectivity the day they arrive, for coordination, registration, payments, logistics and their own safety. After a disaster, local networks are often down or overloaded. A deployable kit brings a field office, warehouse or clinic online within days, and keeps it running for as long as the operation lasts.

  2. What is measured

    Links, use, security and power

    The kit measures itself: availability and capacity of each backhaul link, Wi-Fi coverage and use across offices and warehouses, security events at the gateway and the state of its solar and battery system. Staff see the same status the support team sees.

    Measured
    Link availability · Capacity · Wi-Fi use · Security events · Power
  3. The base node

    Priority, offline and separated

    The node caches updates and maps to save satellite capacity, gives coordination and safety calls priority, and keeps local services working offline when links fail, syncing when they return. The gateway separates staff, partner and guest networks, so sensitive data never shares a network with guests.

  4. Radio and links

    Satellite first, then everything else

    Low-orbit satellite gives broadband on day one where terrestrial networks are down. Cellular is bonded with it where it works, Wi-Fi covers offices and warehouses, and mesh links reach a nearby clinic or warehouse without cables, so the whole compound shares one secured network.

  5. How it works

    From a crate to a coordination call

    A kit arrives at a new field office two days after a cyclone. Staff mount the terminal and access points and power on; the site registers itself and is online within hours. That afternoon the coordination call runs on it, and registration teams start work on a separate, secured network.

  6. From order to operation · Order

    Scope the operation

    The scope reads the operation’s sites, staff numbers, services, expected length, security policy and the shared services already present. Nexus Observatory Inc. returns the kit per site, capacity plan, security design, support and a price per site and per month.

    Plan a deployment
  7. From order to operation · Survey

    Survey remotely, then on site

    Sites are first assessed from maps and partner reports, then on arrival: sky view for satellite, cellular coverage, buildings for mesh points, power, and safe places for equipment. Findings are recorded so the next site in the same area deploys faster.

  8. From order to operation · Permits

    Import, licences and security

    Equipment crosses borders under the relief telecommunications convention where the host country applies it, radio use is notified or licensed, and the agency’s security and data protection officers approve the network design. Every approval is kept with the site record.

  9. From order to operation · Build

    Build ready-to-run kits

    Kits are built and tested with terminals, routers, access points, gateways and nodes configured with the agency’s security policy and networks. Nodes are enrolled with their identities, and every kit runs together for a day before it is packed for shipping.

    Open the Station Builder
  10. From order to operation · Install

    Set up in a day

    Staff or crews unpack the kit, mount the satellite terminal, place access points and mesh points, connect solar power, and power on. The kit registers itself, and the site is online, usually within the first day on site. Crews follow the site safety plan throughout the work.

  11. From order to operation · Commission

    Commission the security

    Each node proves its identity. Link capacity is measured, Wi-Fi coverage walked, network separation and security policies tested, and emergency calling checked. The site enters service when its tests pass and the security officer signs off. Acceptance is recorded with the owner before handover.

  12. From order to operation · Operate

    Keep the operation connected

    The operation sees every site’s links, capacity, use, power and security events. Capacity shifts to sites in the hardest phase, failed links switch to the second path, and security events reach the agency’s team at once. Every alert and action is kept on the record.

  13. From order to operation · Maintain

    Support until the end

    Remote support handles most faults; spares travel with logistics; software and security updates roll out in rings. When the operation ends, kits are recovered, wiped, refurbished and returned to the stock for the next deployment. Maintenance history stays with each site for its whole life.

01The place and its hazards

Where it runs, and what can go wrong.

Operating contextHumanitarian operations depend on shared connectivity services, and the international convention on telecommunications for disaster relief eases the import and use of equipment across borders. Information security is managed to the international standard, and data about affected people is handled under humanitarian data protection guidance.

Hazards

  • No working networks after a disaster
  • Satellite capacity that is costly and quickly saturated
  • Power cuts and fuel shortages
  • Theft of equipment
  • Sensitive data about affected people exposed on open networks

02What must be measured

What, where, how often, and under which rules.

Radio and links

Satellite

Low-orbit satellite gives a field office broadband on day one, where terrestrial networks are down.

Radio and links

Public cellular

Cellular is bonded with satellite where it works, to add capacity and a second path.

Radio and links

Wi-Fi

Wi-Fi covers offices, warehouses and common areas for staff and partner devices.

Radio and links

Mesh network

Mesh links reach nearby buildings and a clinic without cables.

Edge computeThe node caches software updates and maps to save satellite capacity, shapes traffic so coordination and safety calls come first, keeps working offline when links fail and syncs when they return, while the gateway separates staff, partner and guest networks.

PowerSolar panels and batteries in the kit run the site through power cuts; the kit reports its own power so staff can shed load before it fails.
